There's one thing to keep in mind while watching "The Instructor": you're not having a stroke. Remain assured that it's not you having a medical emergency, it's just the 1981 release's almost complete inability to tell a simple story of revenge. It's a martial arts extravaganza from writer/director/co-star Don Bendell, who has a vision for stunt moves and dark displays of crime and punishment, but he's caught working on several ideas for his endeavor, and none of them connect smoothly. "The Instructor" is a wild ride that often makes no sense, reflecting the work of a first- time filmmaker (actually, his only movie) who was in over his head, believing the visual power of karate action would be enough to support the whole effort. Go into this one expecting technical and editorial precision, and the room will start spinning immediately. Accept the ride as it is, and there's some amusement to be found, especially when rough physical confrontations arrive. Read the rest at Blu-ray.com
